How to find Final Velocity? Report Abuse. final velocity = initial velocity + acceleration times time F = ma Solve the second equation for acceleration because you know the force and the mass. Plug that answer into the first equation; you know the initial velocity as well as the time. So you know everything you need to on the right side of the first equation. You should get the answer.

- Acceleration is a measure of how much the speed increases each second. It can be calculated using the equation. acceleration = resultant force (newtons, N) divided by mass (kilograms, kg). One model rocket has a mass of 50 grams and a rocket engine that produces a thrust of 5 N for 1 second.To find the weight, 50 g needs to be changed into kilograms by dividing by 1000.t can be calculated using the equation. acceleration = resultant force (newtons, N) divided by mass (kilograms, kg). One model rocket has a mass of 50 grams and a rocket engine that produces a thrust of 5 N for 1 second.

Quiz on Galaxy Clusters and AGN To figure this out, multiply the number of galaxies by the mass of each galaxy in solar masses and then multiply by the number of kilograms in 1 solar mass (2x1030). When you do this out you should get 2x1044 kg. Now put the values for the mass and radius that you found into the escape velocity formula, v=(2GM/R) 1/2.

Physics 1 3. To calculate the acceleration, we will use the equation v f v i 2 ad 2  . In this case, v f is the instantaneous velocity calculated in step 2, v i is zero (the ball starts at rest), and d is the distance the ball has dropped when we record v f, i.e. 3m.

How Do I Calculate Resultant Velocity? Find the magnitude and angle for each velocity given. First you want to find the angle between each initial velocity vector and the horizontal axis. This is your angle (theta). The speed given is the magnitude of velocity. Be sure to keep your magnitudes and angles organized. Calculate the x and y components of the individual velocity vectors.

- Because the momentum is p = mv, then. The 1kg mass will have and the 10kg mass will have. Clearly the one with less mass will have to have a greater velocity in order to have the same momentum. The kinetic energy can also be found, and for the 1kg mass is, while the kinetic energy for the 10kg mass is.

- t = time the object is in motion (in seconds) h 0 = the initial height (in feet or meters) from which the ball was dropped or launched v 0 = the initial velocity (in ft/sec or m/sec) of the object when it was launched. If v 0 < 0, the object was propelled downward v 0 = 0, the ball was dropped from rest with no initial velocity

- So let's set the forces equal and solve for the velocity: $$v^2 = \frac{2\mu m g}{\rho C_d A}$$. We'll be very ballpark about this. The density of air is $\rho \approx 1.2 \text{ kg/m}^3$. I'll say your mass is $50 \text{ kg}$. Per this paper, we'll say $C_d A \approx 0.84 \text{ m}^2$. Per this thread, we'll say $\mu = 0.4$. Putting all these numbers in gives us $v \approx 20 \text{ m/s}$, or about 45 mph.

- The kinetic energy is zero at v=0 (when γ = 1), so that at rest, the total energy is the rest energy. So a mass at rest in some inertial reference frame has a corresponding amount of rest energy equal to: All masses at rest have a tremendous amount of energy, due to the proportionality factor of c 2.

- Granite is a good example of an intrusive igneous rock. Extrusive rocks cool above the earth's surface and crystallize very quickly, as a result are finer grained. Extrusive rocks are released from the earth in the form of volcanic eruptions, which occur both on the continents and on the ocean floor.ntrusive igneous rocks is formed from magma that cools, solidifies, crystallizes, and hardens slowly within the earth's crust, and this makes its crystals large.

Q & A: Acceleration, Velocity, Distance, Time The basic equation for solving this is: d = vt + (1/2)at2. where d is distance traveled in a certain amount of time (t), v is starting velocity, a is acceleration (must be constant), and t is time. This gives you the distance traveled during a certain amount of time. If you know any 3 of those things, you can plug them in to solve for the 4th. So if you only know v and d, you can't solve for a unless you also know what t is (i.e. what time was d measured at).
